There have been some minor side effects, but scientists at Oxford University say their experimental COVID-19 vaccine has produced good early results.
The study conducted on about one-thousand people prompted a protective immune response in hundreds of people who got the shot.
Dr. Adrian Hill says the vaccine does well at triggering both arms of the immune system.
He says neutralizing antibodies are produced, molecules which are key to blocking infection and that the vaccine also causes a reaction in the body's T-cells which help to fight off the coronavirus.
